CHURN.

SPECIFICATION forming part of Letters Patent No, 361,458, dated April19, 1887.

Application filed January 1887. Serial No. 223,645. (No model.) I

To all whom, it may concern.-

Be it known that I, ISAAC L. SINGER, of the city, county, and State ofNew York, have invented certain new and useful Improvements in Churns,of which the following is a specification.

This invention relates to'certain new and useful improvements in rockingchurns; and the object of my invention is to provide a churn in whichbutter is produced very rapidly without any waste of power.

The invention consists of the construction and combination of parts anddetails, as will be fully described and set forth hereinafter, andfinally pointed out in'the claim.

In the accompanying drawings, Figure 1 is a sectional plan view of myimproved churn. Fig. 2 is a side view and partial longitudinal elevationof the same. Figs. 3 and 4 are side views of two racks and pinions. Fig.5 is a face view of one of the dashers-in the creambox. Fig. 6 is ahorizontal sectional view of the same.

Similar letters of reference indicate corresponding parts.

The cream-box A, having the hinged covers B, is provided with legs 0,fastened on rockers D, mounted to rock on a base, E, at each side ofwhich a standard, F, is provided. At the upper end of each standard aslotted frame, G, is secured, one of which frames is provided with arack, G, in the bottom edge of the slot, and the otherwith a rack, G, onthe top edge of the slot. With said racks the pinions I 1 engage, whichare mounted on the opposite ends of shafts H H which are mounted insuitable journals in the sides of the cream-box, and at their inner endsare journaled on a bar, T, in the box. On each shaft-a rotary dasher, KK is mounted within the cream-box, said rotary dashers consisting ofblades held between two circular pieces fastened by spokes on the Asemicircular top part, L, is provided on the top of the cream-box abovethe rotary dashers K K and has a hinged coversection, L.

At each side of the rotary dashers a transverse detachabledasher-plate,M,is provided in the cream-box, saiddasher-plates beingprovided with tapered apertures N, which are alternately tapered inopposite directions. Two arms, 0, project from each end of the cream-boxA, and are united by a handlerod, P.

A plug, Q, closes an aperture in the bottom of the cream-box for turningoff'the butlermilk.

The operation is as follows: The cream-box is rocked in the usualmanner, and as the pin ions H H engage with the racks in the top andbottom of the slots G and G, respectively, it is evident that the tworotary dashers are at all times reciprocated in opposite directions.

The cream is also dashed through apertures in the dasher-plate M andthrown forward and The cream-box and the several parts can he cleanedvery rapidly, and the entire churn is a very simple construction.

Having thus described my inventioml claim as new and desire to secure byLetters Patent- The combination,with a rocking cream-box, of twotransverse shafts journaled in the same in line, a rotary dasher'mountedon each shaft, and a pinion on the outer end of each shaft, and fixedslotted frames at the sides of the box, and having racks engaging withthe pinions, of which racks one is formed on the bottom edge of the slotin the frame and the other on the top edge of the slot in theframe,whereby the rotary dashers are'reciprocated rotatively in oppositedirections while the boxis being rocked, substantially as shown anddescribed.

In testimony that I claim the foregoing as my invention I have signed myname in presence of two subscribing witnesses.

ISAAC L. SINGER.
